^^ It WAS the subs.
We brought on Naylor at LB for Roberts. Naylor is completely right-footed. Their winger just turned him inside out. All of the later goals came down that side.
Bryson was replaced by Bavies - who doesn't know the first thing about helping the defense, hence our covering midfielder went off just as they started coming at us. A protected back 4, in the space of 2 subs, became effectively a decent back 3 plus 1 played completely out of position, with no cover from midfield at all.
Tyson will be fine this season. Now he's off the mark, his confidence will have had that pick-me-up that it never got last year.
